Overlaying a StackLayout on another StackLayout does not block interaction

[alfarajali]

Description

I overlayed two Stack Layouts on top of each other using AbsoluteLayout and I was still able to interact with the button in the StackLayout . Is this expected because to my knowledge the second StackLayout should block interaction with the main StackLayout.

Steps to Reproduce

1. Create a .net MAUI app
2. Copy below code to the XAML file:

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="MauiApp2.MainPage">

    <AbsoluteLayout>

        <StackLayout AbsoluteLayout.LayoutFlags="All"
                     AbsoluteLayout.LayoutBounds="0,0,1,1"
                     Margin="5">

            <Button Text="Clic Me!" BackgroundColor="GreenYellow" Clicked="Button_Clicked"/>
        </StackLayout>

        <StackLayout AbsoluteLayout.LayoutFlags="All"
                     AbsoluteLayout.LayoutBounds="0,0,1,1"
                     BackgroundColor="Gray"
                     Opacity="0.6">
            
        </StackLayout>
        
    </AbsoluteLayout>
    
</ContentPage>

3. Copy below code in the code behind file:

namespace MauiApp2;

public partial class MainPage : ContentPage
{
	public MainPage()
	{
		InitializeComponent();
	}

	private void Button_Clicked(object sender, EventArgs e)
	{
		DisplayAlert("", "Hello World", "Cancel");
	}
}

4. Run the app
5. Click the button (which is placed in the first StackLayout) and it will fire the alert; the second StackLayout should block interaction with the first one.

Is there any workaround to address this requirement?

still not working

There was a workaround found in https://github.com/dotnet/maui/issues/9153#issuecomment-1295699420

Simplest workaround for me was adding an empty TapGestureRecognizer to the view that's over top.

As mentioned in the other issue https://github.com/dotnet/maui/issues/9153#issuecomment-1295699420 this is only an issue on Android as by default the other platforms intercept touches - Android does not. This is why in this PR: https://github.com/dotnet/maui/pull/13725 we have to add special code to make Android work like the rest.

It is also simpler to use this XAML:

<Grid>
    <Grid Margin="10">
        <Button Text="Click Me!" BackgroundColor="GreenYellow" Clicked="Button_Clicked"/>
    </Grid>
    <Grid BackgroundColor="Gray" Opacity="0.6" />
</Grid>

I can see that all the issues related to this have been closed, but are there any plans for this issue?

Same problem occured on iOS platform, on version 8.0.61

Is there any progress? Or workaround?
